BOTTLE-CLOSURE.

Specification of Letters Patent. I Patented J 3,111. 13, 1920.

' Application filed May 22, 1917. Serial No. 170,120.

To all whom it may concern:

Be it known that I, WULF SILV'ERMAN a citizen of the United States of America, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Bottle- Closures, of which the following is a speclfication, reference being had to the accompanying drawing, forming a part thereof.

My invention relates to new and useful improvements in bottle closures and lts object is to provide a simple, inexpensive and eflective device tobe attached to the neck of a bottle or the like, by means of which the bottle may be tightly sealed but which by a simple manipulation opens the bottle so that the contents thereof may be poured out.

More specifically, my invention consists in certain novel construction and arrangement of parts whereby both a tubular and a disk-like valve are combined to provlde a complete and tight closure of the bottle, with a hollow extension of the tubular valve carried out to a convenient location for manipulating the device and through which the contents may be poured when the valves are open.

In order that my invention may be thoroughly understood, I will now proceed to describe the same in the following specification, and then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure l is a side elevation of a dev ce made according to and embodying my 1nvention, with one of its parts in section 1n order to show more clearly the construction of parts inclosed thereby.

Fig. 2 is a sectional elevation of the structure shown in Fig. 1.

Figs. 3 and 4 are sectional plan views of the same device, the sections being taken respectively on the lines 3-3 and 44 of Fi 1.

Fig. 5 is a sectional elevation of another structure which also embodies this invention.

Fig. 6 is an elevation partly in section of a modified form of the device shown in Fig. 5.

Like characters of reference designate corresponding parts in all the figures.

10 designates a shell preferably stamped out of sheet metal. The lower end of this shell is constructed to form screw-threads 11 which are adapted to fit over similar threads formed on the neck of a bottle (not shown). The upper part 12 of this shell is bent inwardly to form a flange which is so constructed that it forms two inclined earns 13. This flange is cut away at 14 at two diametrically opposed points at the low part of the cams 13, and midway between these cuts, or at the high parts of the cams the flange is slightly depressed as at 15.

16 is a collar of rubber or the like which is pressed firmly into the shell 10 and may be cemented thereto if desired. It is provided with a central circular hole 17 of the same diameter as that of the hole in the flange 12.

20 is a tube which fits the holes in the flange and in the rubber collar and is capable of both turning and sliding therein. The bottom of this tube is expanded around and pressed against a disk 21 of larger diameter than that of the h0lef17. A flange 22 is formed thereby which seats against the rubber collar 16 and the disk 21 closes the lower end of the tube. The tube 20 is further provided with perforations 23 so placed that when the flange 22 is against the bottom of the rubber collar, they are within the collar and closed by it.

24 designates a pair of diametrically opposed ribs which project from the outer surface of the tube 20 and extend upwardly from the cams 13 when the device is closed. 30 is a spherically shaped stampingwhich is provided with two circular openings in axial alinement. The upper of these openings designated by 31, fits around the upper end of the tube 20, and the stamping 30 is afiixed to the tube at this circle. The other opening 32 forms a sliding fit over the part 12 of shell 10.

Before more specifically describing the structures shown in the remaining figures of the drawings, I will point out the operation of the device illustrated in these Figs. 1-4.

The ball 30 is grasped in the fingers and turned around until the ribs 24 are in alinement with the cuts 14 in the upper, flange of the shell. The tube 20 is then pushed downwardly as far as it will go. This results in moving the flange 22 away from the rubber collar 16 and in moving the tube into such a position that the perforations 23 therein are below the rubber collar. The contents of the bottle to which the device is attached may be poured out through the tube 20.

To close the device the tube is raised. The first result of this movement is to draw the part of tube which has the perforations 28 up into the rubber collar. This of itself will close the bottle. But by continuing the upward movement of the tube the flange 22 will be made to seat on the lower surface or" the rubber collar which obviously produces a more perfect seal. When the parts have reached these positions, tie lower ends of ribs 24: are above the lower parts of the cams 13 of the upper flange. A turning movement imparted to the tube will cause these ribs to ride up on the cams 13 thus forcing flange 22 into the rubber collar 16. When the lower ends of the ribs have reached the highest parts of the cams they will run into the depressions 15. The operator will be able by his sense of feeling to tell when this part of the operation has been reached. The cams 13 are preferably oppositely inclined so that turning the tube in either direction will tighten the flange 22. It is to be noted that when the shell 10 is screwed onto a bottle, the lower surface of the rubber collar 16 forms a seal over the upper edge of the bottle.

The length of the ribs 24 may be such that when the tube is pushed downwardly to open the device the upper end of the ribs may be turned under the flange which forms the cam 13 to lock the device in its open position.

The device shown in Fig. 5 is a somewhat simple structure which also embodies this invention. In this figure the outer shell is designated by 40 and its upper flange by d1. 42 is a cork within this shell, the lower part of which is tapered to fit into the neck of a bottle. It is to be understood that the central part of flange ll is constructed to form cams such as 13 and is provided with cuts such as 14 and depressions such as 15, similar to those shown in 3. The cork is provided with a central longitudinal cylindrical hole 43 to receive the inner tube and has an annular recess 41% to receive the ribs thereon.

In this case the tube is designated by 50, the disk which closes its lower end by 51, its lower flange by 52, the perforations by 53, and its ribs by 54. The upper end of the tube is extended beyond the ribs 5-4;, and is flared outwardly as at 55 to form convenient means of manipulating the device and a suitable pouring spout.

In Fig. 6 the shell is designated by 40 its flange by 4:1, and the cork by 42*. The lower part of the cork is not in this case designed to it tightly into the neck of a bottle, but the attachment to the bottle, a portion of which is shown at 56 is effected by crimping the lower edge of the shell dO under an annular flange on the upper end of the neck of the bottle as at 15. The inner tube is like that shown in Fig. 5 and its parts designated by the same reference numerals.

It is obvious that the operation of the structures of Figs. 5 and 6 is similar to that previously described.

I have illustrated and described several embodiments of my invention in order to show that it is not limited to any specific construction. In fact I intend no limitations other than those imposed by the appended claims.

VVhat I claim. is:

1. A. bottle closure comprising a collar having a continuous cylindrical inner wall, a shell "for holding the collar and for aiiixing said collar to bottle, a tube slidably and rotatably fitted within the collar and forming a tight joint with the wall thereof, said tubebeing closed at the bottom and having a flange at its lower end extending over and adapted to be seated on the lower end of said collar, said tube being provided with perforations so disposed that they are within and closed by said wall of the collar when the tube is raised but below the lower end of the collar when the tube is moved downwardly to remove its flange from its seat on the end of the collar, a flange at the upper end of said shell constructed with a cut arranged to receive and guide a rib on the tube, and a longitudinal rib projecting from the tube terminating above theshell flange when the tube is raised to a position with its flange seated on the lower end of the collar, said shell flange beinginclined upwardly from its out to form a cam for the lower end of said rib, whereby the tube flange may be forced onto said lower end of said collar, said tube being provided with perforations so disposed that they are within and closed by said wall of the collar when the tube is raised but below the lower end of the collar when the tubeis moved downwardly to remove its flange from its seat on the end oi the collar, a flange at the upper end of said shell constructed witha pair of diametrically opposed cuts to receive and guide ribs on the tube and a pair of parallel ribs projecting from the tube and terminatabovethe shell flange when the tube is raised to a position with its flange seated on the collar, said shell flange being inclined upwardly in opposite directions from its cuts to form cams for the lower ends of the ribs, whereby the tube flange may be forced onto said lower end of the collar and provided with depressions at the upper part of said cams for receiving the lower ends of the ribs.

3. A bottle closure comprising a collar having a cylindrical longitudinal opening, a shell for holding said collar, the lower part of said shell being provided with screw threads adapted to engage threads on a bottle to aflix the collar thereto, the upper part of said shell being of smaller diameter and having an intermediate annular flange at its upper end, a tube slidably and rotatably fitted in said collar, said tube being closed at the bottom and having a flange at its lower end extending over and adapted to be seated on the lower end of said collar and being provided with perforations so disposed that they are within and closed by the collar when the tube is raised but below the collar when the tube is moved downwardly, said shell flange being constructed with a pair of diametrically opposed cuts to receive ribs on the tube, a pair of parallel longitudinal ribs projecting from the tube and terminating above the shell flange when the tube is raised to a position with its flange seated on the lower end of the collar, said shell flange being inclined upwardly in opposite directions from its cuts to form cams for the lower ends'of the ribs whereby the tube flange may be forced onto said lower end of the collar and provided with depress sions at right angles to the cuts for receiving the lower ends of the ribs, and a spherical member having circular alining openings, one of which is aflixed to the upper end of the tube and the other of which fits over the upper part of said shell.
